The search for Elizabeth “Liz” Waddell has taken a haunting new turn after her family released surveillance footage showing the North Carolina mother in the final confirmed hours before she mysteriously disappeared during a vacation in Grenada. The newly revealed video has become the centerpiece of an investigation that continues to puzzle authorities, as it captures a seemingly ordinary moment that ended in an extraordinary mystery.

Waddell, a 44-year-old physical therapist from Cary, North Carolina, had traveled to the Caribbean island with a friend for what was meant to be a relaxing getaway. On the morning of July 22, security cameras at their Airbnb recorded her walking toward a nearby jetty before calmly jumping into the crystal-clear water for a swim. Her friend remained onshore, unaware that it would be the last confirmed footage of Waddell before she vanished.

According to her husband, Cailen Waddell, the swim itself appeared routine. After retracing the route personally, he described the water near shore as shallow, calm, and easy to navigate, saying it felt “more like a lake” than the rough Atlantic waters they were used to in North Carolina. That observation has only deepened the mystery surrounding how an experienced swimmer could disappear without leaving behind any obvious evidence.

Investigators believe the surveillance footage shows Waddell swimming before heading toward Grand Anse Beach, but no cameras captured her returning from the water. Authorities are now focusing on a possible sighting later that afternoon, when a group of jet skiers reportedly encountered a woman matching her description several hours after the last confirmed video. Police are working to verify that account and determine whether it could help fill the unexplained gap in Waddell’s timeline.

Despite days of extensive searches involving local authorities, volunteers, and Waddell’s own family, no trace of her has been found. After consulting with investigators, the U.S. Embassy, and officials in Grenada, her husband has publicly stated that he does not believe foul play was involved, though the missing-person investigation remains active as detectives continue searching for answers.

Now, investigators say the most critical unanswered questions are not about the moments captured on camera—but about everything that happened after the footage ended. Until someone can explain Waddell’s movements between her last confirmed appearance and the reported offshore sighting hours later, the final chapter of her disappearance remains one of the Caribbean’s most unsettling unsolved mysteries.
